(2) Current monitoring reference (Pr.56)
• Set the full scale value when outputting the current monitor from terminal FM or AM.
• For calibration of terminal FM, set the full-scale value of the connected current meter when the pulse speed of
terminal FM is 1440 pulse/s.
Set the current to be indicated as the full scale value on the meter (1mA analog meter) connected between terminal
FM and SD.
Pulse speed is proportional to the monitored value of output current. (Maximum pulse train output is 2400 pulse/s.)
• For the calibration of terminal AM, set the full-scale value of the connected current meter when the output voltage
of terminal AM is 10VDC.
Set the current to be indicated as the full scale value on the meter (10VDC voltmeter) connected between terminal
AM and 5.
Output voltage is proportional to the monitored value of output current. (Maximum output voltage is 10VDC.)

(3) Terminal AM response adjustment (Pr.867)
• Using Pr. 867, the output voltage response of the terminal AM can be adjusted within the range 0 to 5s.
• Increasing the setting stabilizes the terminal AM output more but reduces the response level. (Setting "0" sets the
response level to 7ms)
